STEAM-BRAKE FOR SINGLE-TRUCK LOG-LOADERS.

Specification of Letters Patent.

Patented Jan. 20, 1914.

Application filed July 19, 1913. Serial No. 780,082.

To (ZZZ whom it may concern Be it known that I, JAMES A. PER'EGO, a citizen of the United States, residing at Call, in the county of Newton and State of Texas, have invented certain new and useful Improvements in Steam-Brakes for Single- Truck Log-Loaders, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to new and useful improvements in steam brakes and more particularly to a steam brake applicable to a single truck log loader and the primary object of the invention is to provide a device of this character which will quickly, readily and efficiently carry out the purpose for which the same is designed.

A further object of the invention resides in providing a device which is simple and durable in construction, inexpensive to manufacture and one which will be very elficient and useful in operation.

lVith these and other objects in view, the invention consists in the novel features of construction combination and a1 'angement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims.

In the accompanying drawings forming a part of this application, Figure 1 is a fragmentary side elevation of a truck showing my improved brake mechanism applied to use thereon and disclosing parts in section. Fig. 2 is a fragmentary rear elevation of the same. Fig. 3 is an enlarged elevation of the cylinder used in connection with the brake mechanism with parts broken away; and Fig. 1 is a horizontal section as seen on line 4. 4, Fig. 2.

In describing my invention, I shall refer to the drawing in which similar reference characters designate corresponding parts throughout the several views and in which 1 indicates the truck legs, upon the lower ends of which is mounted in the usual manner, the axle 2 supporting the Wheels 2 and my improved device consists in supplying a steam brake to the device for use in con nection with said wheels. To this end, a cylinder 3 is provided and secured to the supporting plates 4, which are in turn bolted or otherwise similarly secured to the legs 1, above the axle. A piston 5 is slidably mounted in the cylinder 3, the rod 6 thereof projecting outwardly through the upper portion of said cylinder and connected with the free end of said rod 6, is a U-shapcd clip or the like 7, to which are pivotally secured the pairs of linking arms 8.

The usual I beam 9 of the loader which extends transversely thereof, has secured to its end, on each side thereof, the angle brackets 10, said brackets being also secured to the truck leg 1, as shown at 11. and formed on each of the angle brackets 10, is a pair of cars 10. Fulcrumed between these cars 10 are the angular arms 12, the extreme upper ends of which are adjustably and pivotally connected to the outer ends of the pairs of linking arms 8. The lower ends of these angular arms 12 have adjustably secured thereto the brake shoes 13 which are adapted to engage a wheel 2". A steam pipe l-it, extending vertically between the legs 1 of the truck, loads at its lower end to the cylinder 3 and the upper end of said pipe, at the upper portion of the loader, connects with a horizontal steam pipe section 15, by means of an adj ustablc elbow joint or the like 17. This pipe section 15 leads to any source of supply (not shown) and it will be seen that at any time should it be desired to stop the movement of the truck, it is only necessary to operate suitable valves, to direct the steam passed through the pipes 1st and 15, to the cylinder 3. As soon as the steam enters this cylinder, the same will force the piston 5 therein upwardly and with the upward movement of said piston, the arms 12 will be swung on their fulcrum points to force the brake shoes inwardly against the periphery of the truck wheel, thus accomplishing the desired result.

From the foregoing description of the construction of my improved device, the operation thereof will be readily understood and it will be seen that l' have provided a steam brake which is simple and durable in construction, ii'iexpensive to manufacture and one which will be very efficient and useful in operation.

While I have particularly described the elements best adapted to perform the func tions set forth, it is obvious that various changes in form, proportion and in the minor details of constructimi may be re sorted to without departing from the spirit or sacrificing any of the principles of the invention.

llaving thus described this invention, what is claimed is:--

1. In a device of the class described, the

combination with a car truck and member supported thereon; of a pair of angular arms fulcrumed intermediate of their ends on said member and having the lower ends thereof projected on opposite sides of a wheel on said truck, brake shoes applied to the lower ends of said arms for contact with the aforesaid wheel, inwardly and downwardly extending linking arms adjustably connected at their outer ends to the upper ends of said angular arms, and vertically reciprocating means connected with the inner converging ends of said linking arms to actuate said angular arms and correspondingly manipulate the brake shoes.

2. In a device of the class described, the combination with a car truck, and a member supported thereon; of a pair of angular arms fulcrumed intermediate of their ends to said member and having the lower ends i,os4,754

thereof projected to points on opposite sides of a wheel of said truck, brake shoes secured to the lower ends of said arms adapted for engagement with the aforesaid wheel, inwardly extending and downwardly converging linking arms adjustably connected at their outer ends to the upper ends of said angular arms, and vertically reciprocating means connected with the inner converging ends of said linking arms for actuating said angular arms on said fulcrum points and correspondingly manipulating the brake shoes with respect to the aforesaid wheel.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.

JAMES A. PEREGO.
